Fantasies of a synth Nick x Sole survivor

The fantasies

You were quite shocked to see a synth fantasize such dirty things. You flipped through his journal, each page filled with scribbles of wishes and the fumes of smoke and oil. Each seductive word made you bite down on your bottom lip, you could just imagine his cold metal fingers against your bare skin. You knew he was hiding something from you. The way he'd always quickly hide his journal when you'd show up and on top of that make pitiful excuses about why you can't see it. Nosiness got the best of you like it always does and now here you are, your stomach in a knot as you read a bot's desires.

"These feelings of mine is confusing, I could never think of having these desires but every time I see her I can feel my chest getting heavy. The doll is so distraught, I want to help her but what can a ol Synth do to please her? Oughta embarrass myself if I say anything"

You knew poor Nick had no confidence. Every time he wrote about a moment that you flirted with him he denied the idea that you are interested in him. The reminders that he was a synth repeated in every page. How could someone love a synth? Why would someone be vulnerable to a synth? You sighed and shoved the journal back in his drawer. Your mind debated what to do, you owe Nick for everything. He helped you with your son, gave you a place to stay, was there for you through thick and thin. He knew your whole life was warped when you left the vault, different commonwealth, different people, different currency. A little smirk creeped on your face when you realized you never payed the detective for his work. Time to pay the detective.

Nick showed up a little later with noodles in his hand.
"sorry y/n, didn't mean for it to take so long". He set the bowl down at the table, sitting down across from you. Your mind scrambled on what to do as you hastily ate your noodles. Nick doesn't seem the one to make any moves, so you'd have to be the one to make them. You slurped another noodle down and looked up to see Nick nose deep in another case, visibly frustrated as he rereads certain sections over and over.
"y/n this case is gonna make me lose my head, these disappearance connect I know it, but I can't put my finger on how" you shook your head and got up
"Nick you overwork yourself, have you ever had a little break?" You purred, as you walked over.
"Oh don't get all sappy with me, it's my job, I just wish sometimes it'd be a bit easier" he leaned back on the chair.
"But sometimes a detective needs to treat himself" you whined, removing his trench coat and hung it on the coat rack. "Tell me Nick what does a synth like you want? What is his desires~?" You purred. Nick started showing signs of nervousness, fumbling for his pack of cigarettes.
"A synth like me want justice, so I oughta finish this case" he took out a cigarette and tried to light it, the lighter not being very helpful.
"Nick~ you're too invested in this case" you pushed the file on the other side of the table "take a break, settle down, even synths are allowed to take a breath" You went behind him and ran your hands from his shoulders down his chest, making Nick struggle with his lighter more. You leaned over and lit the cigarette for him while your mind wonders on how to seduce the synth.
"You're acting a little weird doll" he said, his suspiciousness rising. You tried to play it off.
"Im your partner Nick, am I not allowed to care for your wellbeing?" You could tell Nick was catching on
"Yeah but usually it isn't this...physical" you could feel is chest heating up, a little smirk creeping up your face.
"Oh I can make this a lot more physical, would you like that Nick Valentine~" if he didn't know then he knows now. You could feel him shutter as you sneakily pressed your lips up against his neck. "Oh Nick, you always seem to have an answer but this is the one time I've ever seen you speechless" You smile as you walked around in front of him, moving to kiss him but he pushed you back a little. He lit out a shaky breath
"You're trying to...with me? I know Im all charismatic but I don't have..." you cut him off.
"I know...I know, it's no secret Nick. Let that go" You could see his want for lust sizzled in the back of his mind. His bit his lip lightly
"y/n...I..." you could see his wants of affection boiling in him, enough for him to stand up and walked to you. He stood inches from your face a bit hesitant standing that close to you. He leaned in, kissing you gently. Your hands rans up his back, pulling him closer as you coaxed him to get rougher. As you kissed him you could feel a struggle. His lips left yours as you hungrily chased after him "please~ don't hold back" you plead.
"Oh I won't" he said huskily as he ripped his tie off and he pushed you against the wall. Your heart skipped a beat as he kissed you rougher, sliding his cold metal hand underneath your shirt that sends shivers down your spine. His tongue pressed against your lips and slipped in your mouth making you moan softly. He was gentle yet rough with it all knowing he could hurt me. He would a break from time to time and press his lips up to whisper sweet nothings into your ear. You're heart was beating out of your chest, you never knew how much Nick wanted this, but the feeling of having his lips against your was a piece of heaven. More of his desires spilled out onto you as he picked you up and put you on his desk, knocking some papers over. You barely had anytime to breathe between each kiss, you barely managed to keep up.
"Nick..." you moaned out between a his kisses. Your hand trailed up his chest to pull off his suspenders off and unbuttoned his shirt a little so you could slip you hands in his shirt. His chest was hotter than you expected but still ran your hands up his chest. He separated so he could kiss your neck, laying gentle kisses everywhere "mmm Valentine, my Valentine~" you purred as his lips pressed gently against your neck. You shuttered as he left light love marks on your skin, his face buried in your neck. He bit his lip as he fiddled with the bra strap, jumping when you hear a knock on the door.
"Nick? Are you in there? Did you find any leads to those cases?" Said a woman's voice on the other side of the door.
"Ellie...damnit" he mumbled to himself "Yes Ellie I'll be right there" He looked at you and kissed your cheek and shuffled over to the door and escaped through the door. He looked like a mess. Steam seeped through the cracks of his skin, his spenders were off, his clothes were ruffled and one side even off his shoulder. Ellie looked at worn out synth with concern.
"What the hell did you get yourself into?" she asked, looking at him with confusion.
"Oh uh..." how does he even explain this. To make it better she could hear your quiet pants as you tried to clean up the area. Ellie looked at Nick and crossed her arms.
"Nick did you happen to have a bit of time with you're new assistant?" She questioned, giggling a little. He leaned against the door, love taking over his robotic heart.

"Yeah~ I did...I did"
